Critical Steps
A second round of amplification is not advised as biases in array data have been observed. Mixing carefully at each enzymatic step (1st and 2nd strand cDNA synthesis, IVT) is critical to obtaining good amplification yields, as is incubation of each enzymatic step at the appropriate temperature. A PCR cycler with adjustable heated lid is preferred &ndash; even deviations as small as 2-3 degrees during IVT in an air hybridization oven or water bath hybridiza...

vaccinia virus infection &amp; temporal analysis of virus gene expression: part 2

The family Poxviridae consists of large double-stranded DNA containing viruses that replicate exclusively in the cytoplasm of infected cells. Members of the orthopox genus include variola, the causative agent of human small pox, monkeypox, and vaccinia (VAC), the prototypic member of the virus family. Within the relatively large (~ 200 kb) vaccinia genome, three classes of genes are encoded: early, intermediate, and late. While all three classes are transcribed by virally-encoded RNA polymerases, each class serves a different function in the life cycle of the virus. Poxviruses utilize multiple strategies for modulation of the host cellular environment during infection. In order to understand regulation of both host and virus gene expression, we have utilized genome-wide approaches to analyze transcript abundance from both virus and host cells. Here, we demonstrate time course infections of HeLa cells with Vaccinia virus and sampling RNA at several time points post-infection. Both host and viral total RNA is isolated and amplified for hybridization to microarrays for analysis of gene expression.
